The National Centre for Immunisation Research and Surveillance has been tracking coronavirus transmission in schools in conjunction with Sydney University, NSW Health and the education department.
The study was led by Sydney University paediatric infectious disease specialist Dr Archana Koirala, who says there was not a dramatic increase in transmission in school settings despite high numbers of exposures in the final term of last year.
"Our findings confirm that vaccination of students and teachers as well as other mitigation measures in schools and the wider community can keep transmission low in educational settings," Dr Koirala says.
The data predates the peak of the Omicron outbreak.
Meanwhile, the teachers union has called on the government to continue providing free rapid antigen tests to students and teachers for at least another six weeks.
Parents reported 12,000 positive RATs in the week beginning February 7.
More than 90 per cent of parents have been using the testing kits provided by their schools, according to a recent survey of more than 80,000 parents.

The program, up for review after week four of term, has recently been extended for another six weeks in Victoria, and another four weeks in the ACT.
The testing regime continues to be "essential", the Independent Education Union of Australia NSW/ACT said.

Singing and dancing is allowed to resume in most settings, the two-metre density limit for indoor venues has been scrapped, and QR check-ins now only required for nightclubs and music festivals with more than 1000 revellers.
The requirement to wear face masks will also cease in most settings next Friday.
Business NSW chief executive Daniel Hunter said it meant businesses could now "plan for their future".
